    Accuphase A-48

    CLASS-A 45W/ch STEREO POWER AMPLIFIER

    Featuring a six-fold parallel push-pull architecture with power MOS-FETs, as well as ideal gain allocation realized with discrete semiconductors in an instrumentation amplifier configuration, the A-48 harnesses a wealth of advanced technology. Its outstanding performance is exemplified by a signal/noise ratio of 117 dB, output of 360 watts into 1 ohm (music signals), and a damping factor of 800. The newly designed output protection circuit can detect any short-circuiting of the speaker terminals, for complete peace of mind. This power amplifier is the ultimate instrument for immersive music appreciation on the highest level.
